Variable transfers Between Stacks and Sub-Stacks.

If the data in the sub-stack is stored in a field, then it's really easy:
   put field "Data" of stack "Sub" into myVariable

The mainStack always "knows" where it's sub-stacks are and can grab
data from them directly.

There is no need to use global variables (which are persistant and
will not respond to change unless you script it), just use field data
and retrieve it every time you need it. That way any changes will be
implemented automatically.
